This is one the of the common combination of south Indian lunch.
I love combination of Kappa and fish curry along with rice. It's one of the most popular dish of Kerala. If you're a sea food lover, then you also will fall in love with the spicy Tuna Fish /Choora Meen curry along with kappa.
In Kerala, lunch means it is a heavy process of cooking as well as eating. Usually, unpolished brown rice is used for cooking. Fish fry or fish curry along with vegetable curries are regular for Keralites everyday lunch.
Rice with Tomato Rasam, Tuna Fish curry/Chhora Meen Curry, and Kappa Ularthiyathu/Mashed Tapioca.
